2.    Release of Claims.

(a)    Your receipt of the Severance Benefits [or CIC Severance Benefits, as applicable,] pursuant to Section 1 above shall be subject to and conditioned upon your timely execution and non-revocation of a general release of claims in the form prescribed by the Company (a “Release”) that becomes effective and irrevocable within sixty (60) days following the Date of Termination (or if the Company delivers a copy of such Release to you more than five days after the Termination Date, such time period will be extended to sixty (60) days plus the number of days beyond five days).

3.    Section 409A.

(a)    To the extent applicable, this Letter shall be interpreted in accordance with Section 409A of the Code and Department of Treasury regulations and other interpretative guidance issued thereunder (collectively, “Section 409A”). Notwithstanding any provision of this Letter to the contrary, in the event that following the date hereof, the Company determines that any compensation or benefits payable under this Letter may be subject to Section 409A, the Company may adopt such amendments to this Letter or adopt other policies or procedures (including amendments, policies and procedures with retroactive effect), or take any other actions that the Company determines are necessary or appropriate to preserve the intended tax treatment of the compensation and benefits payable hereunder, including without limitation actions intended to (i) exempt the compensation and benefits payable under this Letter from Section 409A, and/or (ii) comply with the requirements of Section 409A, provided, however, that this Section 3(a) does not, and shall not be construed so as to, create any obligation on the part of the Company to adopt any such amendments, policies or procedures or to take any other such actions or to create any liability on the part of the Company for any failure to do so. Any right to a series of installment payments pursuant to this Letter is to be treated as a right to a series of separate payments.

(b)    Notwithstanding anything to the contrary in this Letter, no compensation or benefits, including without limitation any Severance Benefits [or CIC Severance Benefits], shall be paid to you during the six-month period following your “separation from service” with the Company (within the meaning of Section 409A, a “Separation from Service”) if the Company determines that paying such amounts at the time or times indicated in this Letter would be a prohibited distribution under Section 409A(a)(2)(B)(i) of the Code. If the payment of any such amounts is delayed as a result of the previous sentence, then on the first business day following the end of such six-month period (or such earlier date upon which such amount can be paid under Section 409A of the Code without resulting in a prohibited distribution, including as a result of your death), the Company shall pay you a lump-sum amount equal to the cumulative amount that would have otherwise been payable to you during such period (without interest). References in this Letter to your termination of employment (and like terms) that shall mean and refer to your Separation from Service.

4.    Withholding. The Company will have the authority and the right to deduct or withhold, or require you to remit to the Company, an amount sufficient to satisfy all federal, state, local and foreign taxes (including any employment tax obligations) required by law to be withheld from amounts payable under this Letter.

5.    No Right to Continued Employment. Nothing contained in this Letter will (i) confer upon you any right to continue in employment with the Company or its affiliates, (ii) constitute a contract or agreement of employment, or (iii) interfere in any way with the right of the Company and its affiliates to terminate your employment at any time, for any reason or no reason, with or without Cause (subject to the terms of the Offer Letter, as amended hereby).

6.    Governing Law. The validity, interpretation, construction and performance of this Letter shall be governed by the laws of the State of [Texas/California] without regard to its conflicts of law principles.

7.    Entire Agreement; No Other Modifications. This Letter, together with the Offer Letter, sets forth the final and entire agreement of the parties with respect to any salary severance and/or continued healthcare coverage payable upon any termination of your employment by the Company without Cause or by you for Good Reason, and supersedes all prior agreements, promises, covenants, arrangements, communications, representations or warranties, whether oral or written, by the Company and you, or any representative of the Company or you, with respect thereto. However, this Letter does not supersede any existing rights that you may have, if any, to other types of benefits (for example, a bonus or acceleration of equity awards) (excluding salary severance and/or continued healthcare coverage) that may become payable to you upon a termination of your employment by the Company without Cause or by you for Good Reason pursuant to the Offer Letter or any other written agreement between you and the Company. Except as otherwise expressly set forth in this Letter, the terms and conditions set forth in the Offer Letter shall continue to apply in the event of your termination without Cause or resignation for Good Reason following the date hereof.

8.    Miscellaneous. This Letter may be executed in one or more counterparts, each of which will be deemed to be an original but all of which together will constitute one and the same instrument. No provisions of this Letter may be amended, modified, or waived unless agreed to in writing and signed by you and by a duly authorized officer of the Company.
